RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: Phase I/II trial to study the effect of monoclonal antibody therapy on the body and its effectiveness in treating women who have locally advanced or metastatic breast cancer that was previously treated with combination chemotherapy.

Condition Intervention Phase
Breast Cancer
Biological: monoclonal antibody HuHMFG1
Phase 1
Phase 2

Study Type: Interventional
Study Design: Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open Label Phase I/II Study of Humanized Human Milk Fat Globule-1 (THEREX) in Patients With Locally Advanced or Metastatic Breast Cancer Following Prior Anthracycline and Taxane Therapy

Further study details as provided by National Cancer Institute (NCI):

Study Start Date: May 2003
Detailed Description:


  • Determine the safety and tolerability of monoclonal antibody HuHMFG1 in women with locally advanced or metastatic breast cancer previously treated with anthracycline and taxane-based therapy.
  • Determine the maximum tolerated dose and appropriate schedule of this drug in these patients.
  • Determine the pharmacokinetic profile of this drug in these patients.
  • Determine the tumor response rate, progression-free survival, and median survival of patients treated with this drug.
  • Analyze immunological markers for evaluation of disease status (e.g., in vitro analysis of antibody-dependent cellular cytotoxicity, natural killer cell activity, complement depletion, and tumor markers CA 15.3 and CEA) in patients treated with this drug.

OUTLINE: This is a dose-escalation, open-label, nonrandomized, multicenter study.

  • Phase I: Patients receive monoclonal antibody HuHMFG1 IV over 1-3 hours once every 3 weeks for doses 1 and 2. All subsequent dose intervals are based on individual half-life value of the drug. Patients receive at least 6 doses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of monoclonal antibody HuHMFG1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

  • Phase II:Patients receive monoclonal antibody HuHMFG1 as above at the MTD. Patients are followed at 28 days.

PROJECTED ACCRUAL: Approximately 3-40 patients (3-15 patients for phase I and 19-25 patients for phase II) will be accrued for this study within approximately 12 months.
